Core Planning Reasoning
The Inspector recommended the omission of Condition 3, concluding that the proposed side dormer's design, scale, and location—set back significantly from the road and partially obscured by the neighboring property—would not negatively impact the visual or residential amenities of the area and that the condition would unnecessarily compromise the internal layout.
Decision Maker's Conclusion

- The proposed development does not cause undue injury to the residential amenities of the adjacent property (No. 16 Glendale Park) in terms of overlooking, overshadowing, or overbearing impacts.
- Complying with the Planning Authority's Condition 3 would require the internal relocation of the staircase, which would likely compromise the quality and viability of the ground floor habitable accommodation.
